The biggest advertising spend was on the government's health initiative, Healthier Choices Canberra, on which it spent $104,113.

The program aims to make it easier for Canberrans to find healthy food and drink options at clubs, restaurants, cafes, supermarkets and entertainment venues.

The government also spent $60,217 spruiking its new University of Canberra Hospital and $54,949 on a campaign encouraging people to divert from emergency departments.

A campaign called Kilojoules on the Menu - which aimed to help consumers understand and use kilojoule information to make healthier food and drink choices - set taxpayers back $34,936

All up, the government spent $327,092 on campaigns in 2018, up on the $90,922 spent the year before.

The 2018 figure was the highest advertising spend in the last five years, with 2016 the second highest at $309,242.

The figures came from answers to opposition health spokeswoman Vicki Dunne's questions taken on notice by Health Minister Meegan Fitzharris.

An ACT Health Directorate spokeswoman said the directorate had no set advertising budget. Instead, she said funding was based on "community need for important public health information at any given time".

"Health education and awareness is a priority for the ACT Government," she said.

"We want Canberrans to be healthy and well and ensuring Canberrans have the information they need about their health care options is an important part of this."

She said the opening of two new health facilities last year - the University of Canberra Hospital and the Gungahlin walk-in centre - was a major focus for the government.

The most recent questions on notice also clarified that the "I love free public healthcare" campaign run by ACT Labor did not use any public funds.

The campaign was conceived by Labor to promote the government's nurse walk-in-centres.

"The concept was developed by ACT Labor," Ms Fitzharris said.

"Staff in the minister's office advised on publically available information on public health in the ACT."
